The second generation of multi-die high-output LEDs is here! These are all mounted on a direct-thermal-path copper MCPCB.
This LED is a 3V nominal LED, so unlike the 6V/12V version, it can be run from a single lithium-ion cell using a normal (non zener mod) FET driver.
All MCPCBs are copper direct-thermal-path.
Please note that the XHP50.2 has an extremely low forward voltage. It may be damaged by use with an FET driver and high-drain 18650/26650 batteries! You may have to add resistance through thinner wires, weaker cells, etc. to use a single XHP50.2 with an FET driver!
